There are three fossil fuels we must stop burning if we are to save our planet: coal, oil, and methane (aka “natural”) gas. Coal is declining precipitously. Scientists think we hit peak coal in 2013, and American use of coal has fallen by over 50% in the last 10 years (though, we need to quickly nail this coffin closed considering how dirty and polluting coal is). Oil is seeing the writing on the wall as major automakers commit to electric vehicles. Many think 2019 may have been the year we hit peak oil, and EVs are expected to make the internal combustion engine a “historical technology” by 2040. The faster we historicize petroleum, the better, so please buy that electric car or e-bike today.
Natural gas (aka methane) now comes into sight as the next fossil fuel we need to banish in the quest to rescue ourselves from the most catastrophic climate catastrophe. Burning methane is currently responsible for nearly 25% of all carbon emissions in the US, and its use is growing. Methane is also deeply embedded in many of our homes, and this will make it a challenge to extricate. We aren’t anywhere near hitting peak natural gas usage on our current trajectory.
But, as of recently, some American cities, mostly in California, have recognized the need to eliminate gas and slowly get us off the fossil sauce. In 2019, these leading cities did something that had never been done in the history of our species — they started banning future use of methane in new construction. The idea has been to stop digging a hole that we have to quickly climb out of, so they legislated that no new homes or buildings should be built with methane hookups. This will avoid costly retrofits later. The city-led ban began in California, has reached over 50 cities, and is spreading up the West Coast like a good kind of wildfire.
Enter “Renewable” Natural Gas
Any entrenched industry will fight with all its might not to disrupt revenue streams, regardless of the effects of their products on humanity (see: oxycontin and tobacco). So, it is to be expected that methane peddlers will spend the next crucial decades resisting efforts to ban their product. They’ll use lots of arguments to slow humanity’s inexorable push towards a fossil fuel future. The most ingenious/insidious one that we must quickly debunk is that their carbon polluting fuel is actually clean or has the potential to become so.
Enter, stage right, “renewable natural gas,” or RNG, a brilliant buzzword for a product that companies are counting on consumers to believe in, to continue with business mostly as usual. Renewable natural gas is methane that comes from biological sources like human and cow sewage or landfills. It differs from current methane, which is fracked from the earth’s interior, some of which escapes through pipes, while the rest is burned, adding to our dangerous warming blanket. RNG harnesses methane being created anyway and thus, doesn’t add new layers to our greenhouse problem. A group of nonprofits in my region just released an in-depth look at renewable natural gas and the numbers aren’t good.
How to Make Renewable Natural Gas — Anaerobic Digestion and Gasification
Before we can examine how much RNG our society will be able to realistically produce, let’s briefly talk about the two ways to make renewable natural gas. Even though, as we’ll shortly see, RNG won’t come remotely close to meeting our current gas demand, it still has the potential to be an important, lower-carbon tool in reducing the emissions of hard-to-decarbonize applications (like industry).
The first way to make RNG is through anaerobic digestion technology. This is a process where bacteria eat waste in an atmosphere that doesn’t contain oxygen (anaerobic). Sewage treatment plants and pig farms use this process. They gather fecal matter, bring bacteria to a specific temperature, do a lot of other magic in pipes, and out comes methane gas. Landfills are another source of this methane as wasted food and other fun stuff are eaten by bacteria underground and methane is created as a byproduct.
The second way to make RNG is through thermal gasification, which “uses energy to turn agriculture and commercial forest harvest residues” into something called Syngas. Syngas can then be converted to methane with more processing. According to a large survey by the State of Oregon, “There are currently no commercial-scale thermal gasification plants in the United States that convert biomass into methane. The existing plants produce syngas, which is burned and used to generate heat and electricity.” So thermal gasification is a potentially important, but unproven technology that should not make us believe that we can simply keep burning gas in our homes.
How Much Renewable Natural Gas Could We Conceivably Produce?
In the 2018 Oregon study cited above, (which had many gas industry officials involved in its writing) researchers looked at what we could optimistically hope for from RNG production. The numbers aren’t good. The potential for anaerobic digestion is 4.6% while the potential for thermal gasification is 17.5% of current natural gas usage in the state. So RNG could potentially cover 20% of the methane gas we use today, assuming significant investments in technology and distribution systems that do not exist today – in other words and not anytime soon.Think about it. We could work our tushies off over the next couple, crucial decades, to try to decarbonize natural gas pipes, while the planet is heating up and wildfire smoke is crossing our country coast to coast, and after crucial time and work, we’d still be using 80% fracked, fossil natural gas. If that’s not backing the wrong horse, then I don’t know what is.
Oregon’s numbers are similar to national numbers. Another study found that, nationally, we could hope for about 16% renewable natural gas, and again, this is far in the future and only if we invest heavily in RNG.
Compare that to electricity as a fuel, and you’ll see a stark difference. Right now, the national electric grid gets 20% of its power from renewables and 20% from nuclear, making electricity 40% carbon free. Biden wants to get to 100% by 2035. Oregon recently passed a law to get to 80% clean electricity by 2030 and 100% by 2040. Wind and solar are carbon neutral and are the cheapest and most installed forms of new energy generation. We have the roadmap and the tools to completely decarbonize electricity over the next 10–20 years and are doing so faster than anyone expected. Clean electricity is real, proven, happening and the horse we should be backing.
Electrifying our house and capping our natural gas pipe was one of the best things my family has done for the climate.
Other problems with renewable natural gas
There are other significant problems with renewable natural gas which are highlighted in depth in this brilliant article by Laura Feinstein and Eric de Place. Renewable natural gas isn’t even zero carbon. It is true that it often comes from existing sources of methane, but often those sources of methane could be avoided. Take landfills for example. When we toss food scraps into landfills it creates methane. We could capture that methane to make renewable natural gas or we could compost the food scraps like many cities and nations do, and avoid making that methane in the first place and get the benefits of richer, healthier soil in our communities. Relying on renewable natural gas could thus lock us into wasteful, inefficient practices when other options exist.
Another significant problem is that RNG costs a lot to make. A million BTUs of methane gas currently costs $3. The median cost for the equivalent amount of RNG is about 6 times that, at $18. Yipes! Imagine telling consumers that their gas bills are going to sextuple, and you’ll start to see how viable RNG is as a long term solution.
Scratch the surface, and it’s easy to see how RNG meets the classic definition of a red herring; “something that misleads and distracts us from a relevant or important question.” There won’t be very much of it, and it’s going to be very expensive. Let’s not get sidetracked from real climate solutions. When our local methane suppliers use the word “renewable” to keep pumping fossils into our homes, we need to understand that this is at best a stalling tactic and a greenwash to distract from the dangers of methane gas. Let’s stay focused on more realistic solutions for heating our homes and addressing the climate crisis like electrification.

Elon Musk, who already suggested Tesla invest in xAI, is now setting the stage for the public company under his control to grossly overpay for xAI, a private company under his control that just absorbed Twitter (X).
Anyone invested in a mutual fund that owns Tesla shares could be about to bail out Musk and his billionaire friends.
At $44 billion, Musk knew he was overpaying for Twitter and tried to back out of the deal.
Within a year of Musk taking Twitter private, Fidelity Investments, which invested in Musk’s Twitter acquisition, revalued its investment as being down 65% from its purchase price.

A year later, in October 2024, Fidelity valued Twitter, X by now, at just $10 billion.
That’s not surprising since Musk had Twitter take on $12 billion in debt as part of the take-private deal, and revenue fell by roughly half under his leadership.
To take Twitter private, Musk personally financed the deal with $25 billion of his own and his existing stake in Twitter, $12 billion in debt, and about $7 billion in investment from his friends.
As of October, most of that equity was gone, but Musk wasn’t about to let a loss slide on his record.
In 2023, he launched xAI, a private company under his control that develops AI products. Tesla investors are suing him for breach of fiduciary duty and resource tunneling over the founding of xAI since he had previously stated that Tesla would be a big player in AI and simultaneously threatened not to build AI products at Tesla if he didn’t get more control of the company, but let’s put that aside for now.
When raising money for xAI in 2023, Axios reported on how Musk might use the AI company as a “plan B to save Twitter” and Musk responded:
“I have never lost money for those who invest in me and I am not starting now.”
Who are these people who invested in Twitter with Musk? There’s a long list, but two of the biggest investors are Prince Alwaleed bin Talal, a Saudi Arabian billionaire and head of Kingdom Holding Company, and Larry Ellison, billionaire co-founder of Oracle. Both are close friends of Musk.
VC firms Andreessen Horowitz and Sequoia Capital, Qatar’s sovereign wealth fund, the highly controversial crypto exchange Binance, and the previously mentioned Fidelity Investments have also invested in the deal.
By the end of 2024, those people were basically writing down 80% of their investment in Twitter, as per Fidelity.
However, a few months later, in March 2025, X was somehow valued back at $44 billion as part of a “so-called secondary deal.” Some took this information as news that X had turned around, but many were skeptical that the valuation could have gone from $10 billion to $44 billion in just 5 months.
Sure enough, we quickly learned that the new valuation had little to do with improved financials at X and was instead based on Musk pushing for xAI to buy X at $45 billion through an all-stock acquisition. A company’s valuation is only what someone is willing to pay for it and Musk was willing for xAI to “pay” $45 billion.
In late March, Musk announced that xAI had acquired X in a deal valuing xAI at $80 billion and X at $45 billion, while xAI would take on X’s $12 billion debt.
The world’s richest man was not shy about highlighting the controversial self-dealing here:
It’s worth noting that xAI had raised only $12 billion at a $40 billion valuation with virtually no revenue as of December 2024, and now it’s a $125 billion company, based entirely on Musk’s valuation, with $12 billion in debt.
How does Tesla plays into this?
Musk has promised Tesla shareholders that the Twitter acquisition would be good for the company. That was after he sold tens of billions of dollars worth of Tesla stocks to buy Twitter – sending Tesla’s stock crashing.
Tesla shareholders haven’t really seen a return on that yet unless you count a brief surge in stock price after Trump was elected, with the help of Musk and X, but the stock has since erased all those gains since Trump came into office.
Now, xAI is the plan B.
Last summer, Musk suggested that Tesla invests $5 billion in xAI, but that was before the company acquired X. Musk will need shareholder’s approval for a deal between xAI and Tesla, which would happen at Tesla’s shareholders meeting – generally held in June.
Now, Tesla’s CEO, who has been complaining about his eroding control of Tesla after selling shares to buy Twitter, has greatly inflated the value of xAI through this acquisition of X ahead of the potential investment.
Musk has also discussed Tesla integrating Grok, xAI’s large language model, into its products, specifically its electric vehicles.
A post on X this weekend suggested that this might be happening soon:
ChatGPT, OpenAI’s LLM, has already been integrated in many vehicles, including from the Volkswagen Group, Peugeot, and Mercedes-Benz.
Electrek’s Take
The grift never stops. As I have been saying for years, Musk is not equipped to be an executive of a public company, and this is just the latest example.
If all these entities were private, and he was taking his affluent private investor friends on a ride, I wouldn’t have any problem with this, but Tesla is a public company included in many ETFs and mutual funds. Many people own Tesla stocks without even knowing.
But as Musk said himself, he doesn’t let people who invested in him lose money. Does that include Tesla investors?
I don’t think it does anymore.
There’s an argument to be made that Tesla shareholders should already own Musk’s stake in xAI. That’s what the breach of fiduciary duty lawsuit is about. Musk said that Tesla was “a world leader in AI’ and said that AI products would be critical to the company’s future.
Then, he starts a private AI company and threaten Tesla shareholders that he will not build AI products at Tesla if he doesn’t get more than 25% control over the company. That’s a clear breach of fiduciary duties to Tesla shareholders as the CEO of Tesla, but it will likely take years to solve this through courts.
In the meantime, Musk is pushing for Tesla to invest in xAI, which is now valued at $125 billion – a number completely made up by Musk.
Grok is not a bad product, but it ranks below OpenAI’s ChatGPT and Google’S Gemini in most AI rankings. It also relies too heavily on information from X, which is far from reliable. Most experts see xAI as being way behind OpenAI and other AI companies, which are already generating significant revenue.
Now, I doubt Musk will still push for a $5 billion investment from Tesla. I don’t think that Musk will want Tesla to spend 15% of its cash position on this amid delcinign earnings and a very difficult macroeconomic situation.
I wouldn’t be surprised to see Musk pushing for Tesla to invest in xAI as part of a stock deal.
The timing would be good for Musk. Tesla’s current brand issues, lower deliveries, crashing earnings have led to a much lower share price on top of the crashing US stock market. If Tesla’s share price is lower, Musk can get more shares for his made-up valuation of xAI.
Musk likely owns more than 50% of xAI post X acquisition. A stock deal would virtually result in him getting half of the Tesla stocks that are part of the deal – boosting his stake in Tesla, which has been his goal since selling his stake to buy an overpriced Twitter.
In short, Musk sold Tesla stocks to buy an overpriced Twitter, regretted it and threatened Tesla shareholders to get more shares. Now, he might get Tesla shareholders to pay for the acquisition again at the same ridiculous valuation.
The craziest thing about all of this is that I bet Tesla shareholders are going to approve this scheme.

Specialized has announced a voluntary recall for several of its popular Turbo e-bike models after identifying a safety issue with the chain guard that could pose a fall risk to riders. The culprit? A clothing-eating drivetrain setup that may be a bit too hungry for its own good.
The recall affects Turbo Como IGH, Turbo Como SL IGH, and Turbo Vado IGH models equipped with internal gear hubs (IGH), sold between 2021 and 2024. According to Specialized, certain chain guards on these bikes may allow loose-fitting clothing to become entrapped in the drivetrain, potentially causing crashes or falls.
The recall includes both belt-drive and chain-drive models. Models equipped with traditional rear derailleurs are not part of the recall and remain unaffected.
The issue isn’t widespread in terms of injuries — thankfully, as there have been no reports of serious harm. But as Specialized continues to grow its e-bike lineup, especially in the urban and commuter segment, it’s clear they’re taking proactive steps to ensure rider safety and confidence.

Riders of affected bikes are being advised to stop using their e-bikes immediately and schedule a free chain guard replacement with their local Specialized retailer. The fix will be installed at no cost, and Specialized is footing the bill for both parts and labor.
You can check if your model is affected by visiting Specialized’s official recall notice page, or by contacting their Rider Care team.
This recall lands in a growing category of micromobility safety updates and recalls, as more riders turn to e-bikes and scooters for daily transportation. From battery-related recalls to structural flaws, the increased adoption of electric two-wheelers has put new pressure on manufacturers to catch potential issues early.
While the vast majority of all e-bikes and e-scooters will never see a recall, the growing number of models on the road has seen an uptick in such occurrences over the last few years.
Electrek’s Take
While it’s always disappointing to see a defect, it’s encouraging to see brands like Specialized move quickly, transparently, and without passing costs to the customer.
And let’s be honest: for riders who favor flowing pants, long jackets, or any other long garment, these kinds of things can happen. My wife learned that the hard way when she lost a chunk of her kimono last year when she switched to riding her bike to work every day. Securing long, flowing clothing is just part of the safety procedure for riding bike. It’s good that Specialized is being proactive here, but I think just about any bike could see long garments getting sucked into a chain if conditions are right – or wrong.
I reviewed one of these e-bikes a few years ago and it was an incredible ride. I managed to escape with my pants intact, and I’d still ride one any day. If I owned one though, I’d probably take it in for that free chain-guard swap, though – which is just another example of a benefit of buying a bike shop e-bike as opposed to a direct-to-consumer brand. I love my D2C e-bikes, but having a bike shop help with this stuff, or even reach out to you directly during a recall, is a big plus in my book.

U.S. oil prices dropped below $60 a barrel on Sunday on fears President Donald Trump’s global tariffs would push the U.S., and maybe the world, into a recession.
Futures tied to U.S. West Texas intermediate crude fell more than 3% to $59.74 on Sunday night. The move comes after back-to-back 6% declines last week. WTI is now at the lowest since April 2021.
Worries are mounting that tariffs could lead to higher prices for businesses, which could lead to a slowdown in economic activity that would ultimately hurt demand for oil.

Oil futures, 5 years
The tariffs, which are set to take effect this week, “would likely push the U.S. and possibly global economy into recession this year,” according to JPMorgan. The firm on Thursday raised its odds of a recession this year to 60% following the tariff rollout, up from 40%.
